To all whom it may concern: Y

Be it known that I, ARTHUR Nonnisori MARR, residing. at. Rangiora,Thorner, near' Leeds, in the county of York, Eng- Y Sland, have inventednew and useful Imrovements in Apparatus for Dryin Sized 'arns and Warps,of which the 0 lowing.

' is a' specification.

This invention relates to improvements 19 in machines or apparatus fordrying sized cotton, or worsted, or woolen or other yarns andwarps, andit is particularly applicable to that class of machines known ascylinder sizing machines provided with posi- -tive drivin mechanism andhaving a creel and sizing. ox on one side of the cylinders, and ontheother side a headstock with cooling fan, or fans, conductin rollers,polishing dividing rods, and revo ving yarn-beam 20 'presser.

' The object of this invention is to dispense with the above namedcylinders,which are heated to the required temperature, and.

over and partially around which thensized 2 wet yarns or warps are madeto proceed or pass in their passage from the creel and sizing box to theyarn be'am,and to substitute therefor an air drying chamber rot-avertical ty e provided with anumber of pard rollers, heating apparatus.and fan or fansfor drawing and circulating the heated air simultaneouslythrough the sev--- 'cllilamber D is preferably open to the atmosp ere.

from which the war or sheet is led. to,. the chamber of'the rying mac'ine. All the above parts are of the usual and r ordinary type andwillbe readilyunderstood by those engaged inthetrade. with out furtherdescription.

Between the 'sizingbox and headstock portions of a sizing machine isinserted the vertical air drying chamber of any suitable size and shapein cross section, suchas rectangular as disclosed in the accompanyingdrawings. The vertical air drying'cham ber takes the place of one, two,or more revolving drying cylinders which are usually employed in thisclass of machine. The vertical air drying chamber is wholly or 7partially formed of wood, or irompra combination of twoor more of.summaterials "and it is horizontally divided into two chambers orcompartments G, D, of unequal size and area. -The upper and largercompartment 0 is employed for drying purposes and the smaller one Dwhich islocated m the base of the structure s for the reception of aportion of the heating apparatus, and one or more fans which areemployed for causing the air first to; enter the drying chamber C,- andthen to circulate through the several verit is-divided, and to withdrawthe air and v moisture therefrom: into the fan; the lower A convementway for forming the drying chamber isto makea framework offour 1uprights h, preferably-of channel-beam construction, with ends and sidesin sectionsand arranged between a number of spacedand suitably formedhorizontal cross pieces or beams 72 fixed by their ends to the uprightsThe sections are made in panel form, fo'rconvenience of transit anderection, and placed in position between each 1 I pair of cross beams71, being strengthened by 1 0 suitably constructed cross stays j whichform part of each section. By employing a number of horizontal. crosspieces or beams I the frame work in the first case is built up inskeleton form, and divided horizontally N into the two chambers C D. Theinner walls of the structure'are lined with wood,

orother suitable materialnot bein afiected to any appreciable extentclimatic or he lower por 119 tion of one or more sides of the dryingchamber is made in panel form Z and provided with access doors m fittedwith glass.

The upper chamber C is divided by partitions it and into any requirednumber of vertical compartments, or sections, for example, first intofour vertical compartments p by the partitions 0, and afterward eachvertical compartment p is again sub-divided by the partitions n. Thevertical partitions n which come against the heating or radiating pipes00 and y are formed of strips'of sheet iron, as shown at Fig. 4, andthey are made secure to the pipes of the heaters a: and

3 and are retained in position by the bolts 2 arranged to pass throughthe cross bearers 1 which are formed of iron. The cross bearers 1 alsoaid in retaining the radiator pipes of the heaters w and y in a levelposition. The portions of the partitions n above the top of the radiatorpi es a: and 3/ are either formed of wood, or 0 sheet iron,

The chamber C is closed at its top with a cover 9 preferably having anumber of 'openings therein, one foreach compartment 1) and being closedby doors r. In the top of each compartment '77 is mounted insultableball or other bearings a roller 8, andat the bottom of each partition 0is a roller 25 extending partly into each of the adjacent compartments.The first tworollers s and t over which the Warp or sheet passes arepreferably lagged and provided with driving elements u, 'v, disclosed inthe form of sprockets. The remaining rollers preferably are not lagged.The rollers't'are ar-- ranged at a suitable distance above the bottom ofthe vertical chamber C.

The warp or sheet of yarn to be dried as :itleaves the rollers e and fof the sizing box is carried upward and downward and tend fromthe bottom2 of the drying chamher 0 to the underside of the rollers 8 whilethrough the compartments over the rollers s, t in the sinuous manner asshown at Fig.

1 of the drawings. The rollers s are arran ed at a suitabledistancebelow Q18 top Q o the chamber C. The partitions n exthe partitions,oextend from the top 9 of the chamber C down to, and near the top,

of the rollers t. By this means and by closing the vertical chamber C onits bottom, except providing openings 3 and 4 therein respectively forthe entrance of the warp orsheet gr and the heated air for dryingpurposes,

provision is made for leading the war or s eet'giup and down between thejwho e or any number or the compartments so asto besubjected' to theaction of the heated air- Which is driven into the chamber.

by thefan- 5." The partitions are arranged rollers and are provided-foreach layer of to beabout the center of their respective yarn, or warp,or sheet being isolated for drying purposes.

ipeaora On the partitions m. and 0, and also on one or more of the innersides of the vertical chamber C, are fixed horizontally at suitabledistances apart a number of triangular shaped blocks 6 for contractingthe size of thecompartment, and also for directing the air currents onto and through the wet warp or sheet 9, thereby causin them to slightlyvibrate andseparating t em from one another, and also preventing theindividual threads forming the warp or sheet adhering to each other. Theblocks 6. are made the full width of the partition in each compartment.At Fig. 1 it will be seen that on the entrance side of the verticalchamber three of such horizontally angular shaped blocks are fixed toits inner side, and at the first division 97, only one of such angularshaped blocks 6 are used, and in other instances it will be notedthatsuch angular blocks '6 are placed on both sides of the partitions.The number and position of the angular shaped blocks may be varied ascir- '3 cumstances', and the number of the warp or sheet 9, requires. Insome cases it'may be found necessary 'to-employ more of thesehorizontally fixed angle blocks 6 than in other cases, therefore it mustbe distinctly understood that they ma be varied as required. The sidesof .t e blocks are-reguired to be at such an angle that they will irectan upward or downward current of warm air against and through the warpor sheet g.

j The heaters :22 and y are radiators of the,

ordinary type formedof a number of pipes of varying lengths arranged-inrows, .and-

extend the full width oft-he warp or sheetg. v v The pipes in one 'rowofthe radiators m,-which are laced in the chamber D,- pass through t eopening 4 and extend asuitable distance within the vertical chamher fordrying the warp or sheet 9 as .it

passes up to the first r0 r .9 and down to the first roller Z. Ifdesired two. or more radiators a: may be used in chamber D for obtaininga variation of temperature; An additional radiator y is provided forocca sional use in very cold or very wet weather,"' 4

and for circumstances when extra heat is required for drying urposes.The heaters or radiators w and y eing of ordinary construction will bereadily understood without further explanation.

5 is "a fan of any ordinary construction "placed" in the chamber D, andit may be rovided with one or more suction inlets. n the. drawings theoutline of a fan of the Sirocco type is shown provided with two suctioninlets 7 and 8.

9 is the fan shaft upon which the driving I pulleyor motor 10 ismounted.

To each suction inlet '7 and 8 is provided a funnel shaped opening orair trunk 11, 11, as shown by the dotted lines yawn circulate throughthe compartments of the said chamber and to be drawn out therefrom throuhsuitableopenings or apertures. The

- air, a er passing through the fan or fans 5 is discharged through theoutlet 13 on to the heater or radiator a and passes through opening 4into the drying chamber.

In practice ithas been found that none of.,- the rollers s and t need bedriven from the elements u, "v as the frictional con drivi tact b thewarp or sheet passing over roller is found to be suflicient.

Around the top of the drying chamber C may be fixed the supports 14 towhich thelatform 15 is fixed, and around the platibrm may be fixedthe'rail 16 carried by the pillars 17. This platform provides a readymeans for getting to the top rollers for lubricating "and adjustingpurposes, and-' also for openin or closin the doors 1'. The bya ladder not platform may e reache shownin the drawings.

The action of the apparatus is as follows :The warp or sheet 9 as itleaves sizing box p'ortion'.of a sizing machine is passed through theopening 3 which extends the full width of the chamber C and it is thencarried up and passed over the first roller 8 downto the first roller tand is led' in -a:sinuous manner up and down, and over and under therollers until it reaches the bottom conducting roller 18 and from thenceit is drawn and divided1through the headstock and wound on to the loombeam. As the warp or'sheet g is drawn through the verticalcompartmentsthe'air that has been drawn into the-fans is passed throughthe air trunk 13 and after passingamong the tubes-or coils of the heater.7: it enters the drying chamber C through the opening 4 and passes upthe first chamber or compartment and in so doing comes in contact with eblocks 6. In the ascent of the air. through one compartment it willstrike I against the undersurface of the blocks, and

f-J'as it passes down on the opposite side, say, of partition's n and oit will come in contact with the upper sides of another set of blocksand as it comes in contact with each angularface of'the blocks 6, theair will be directed against and through the traveling sheet I therebycausing the latter to slightly vibrate for separating the threads of am.so

The

.fan by being connected at 12 with the last vertical compartment ofchamber C will draw the air through the whole of the comartments, andback into chamber D and an 5, thereby more quickly and evenly drying theyarn. By isolating each layer of lber C and .iof the cylinder siz1n"yarn or war in the compartments as described permits of the warm airfollowing the same sinuous path as the war or sheet g at the same or ata difl'erent sur ace speed, and also allows the maximum time for contactbetween the warm drying air and the wet warps, and further, in the eventof broken ends, such ends ane'carried along with the air current. Byopening the doors 1 at the top of one or more ofthe compa'rtments, moistair is allowed to-escape, or cold. air may be drawn into suchcompartments when and as desired. 1 a The above described verticaldrying chamrts connected therewlth are arranged to orm part of, andsupersede the cylinders of a sizing machine, and the parts machine notherein particularly mentione or described may "be of the usual andordinary construction.
